Efficiency: Bite is a cost efficient card because it gives your Hero the ability to do 4 additional damage and gives you 4 armor. Using Heroic Strike as a reference, the +4 Hero attack is worth 2 mana and the 4 shield is debatably worth 2 mana. Therefore, this card has an average cost efficiency.

Uses and Tactics:

Using this attack on the enemy Hero has the advantage of letting you keep the 4 armor and dealing 4 damage.

This can be combined with Claw or the Druid's Hero Ability to increase the armor and damage.

This card is about half as card efficient as Claw.

Using Savagery after playing this card gives you a powerful 1 mana removal card.
